Abstract: A holographic external call device for an elevator, which includes a device shell. One side of the device shell is provided with a sensor mounting hole, and a gesture sensor is installed in the sensor mounting hole. An optical module is installed, one side of the optical module is provided with two screen installation grooves, the two screen installation grooves are both installed with a screen, and the bottom side of the optical module is provided with a main board. The screen produces an image after power on, which affects the light reconstruction in the optical module to generate an image in the air, and then the finger clicks on the image in the air. The gesture sensor will sense the gesture and send the command for the main board, addressing cross-contact infection problem caused by using the elevator outbound button to call the elevator without actual physical contact.

Abstract: A holographic elevator control box, which comprises a housing and a first cover plate. The surface of the housing is fixedly connected with a first cover plate through bolts. The inside of the housing is provided with a holographic optical module. The holographic optical module is fixedly connected with the housing. The surface of the holographic optical module group is fixedly connected with a screen. The surface of the first cover plate is fixedly connected with a main board. The screen is connected with the main board through wires, and the top of the housing is installed with an induction module. The holographic elevator control box can address cross infection so that when using the elevator with the device, the interaction between the person and the elevator can be realized by clicking, sliding and other gestures on the image generated by the equipment in the air.
